MECHANISM FOR GRINDING BANDS UPON THE SURFACES 0F WINE-GLASSES.

SPECIFICATION forming part of v Letters Patent No. 236,432, datedJanuary 11, 1881.

Application filed November 8, 1880.

To all whom it may concern:

Be it known that I, JOHN B. HIGBEE, a citizen of the United States,residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inMechanism for Grinding Bands upon the Surfaces of Wine-Glasses, Goblets,and other Articles of Glassware; and I hereby declare the following tobe a full, clear, and exact description thereof, reference being had tothe accompanying drawings, in which- Figure 1 indicates a perspectiveview of my improved apparatus, showing the grindingpencils andpencil-arms adjusted to simultaneously produce a series of bands uponthe surface of a wine-glass. Fig. 2 indicates a side elevation of thesame with the center pencil and carrier or arm adjusted in position forgrinding and the remaining pencils and arms thrown backward away fromthe surface of the article to be banded.

Like letters indicate like parts wherever they occur.

The object of my invention is to simultaneously produce series of bandsupon the surfaces of goblets, wine-glasses, and other articles ofglassware in a perfect state, and in an expeditious and economicalmanner.

To this end it consists in the combination, with a horizontally-rotatinghead-stock and tail-stock adapted to clamp and rotate the article to beoperated upon, of a series of laterally-adjustable pencil-carriers, eachcarrier independently pivoted and adapted to rise and fall by its owngravity, so as to accommodate itself to any inequalities over which thepencil passes.

I shall now describe myinvention more fully, so that others skilled inthe art may make and use the same.

In the drawings, Figures 1 and 2 indicate the improved apparatus.

A indicates the bed-plate.

B indicates one of the standards, which is perforated transversely atits upper portion by an orifice which is of uniform diameter from theinner side of the standard to a point near its center, where thediameter of the orifice is suddenly reduced, forming a shoulder upon itsinterior. A spiral spring is inserted in this (No model.)

orifice, and rests against the shoulder, and its other end bears againsta shoulder formed on the tail-stock b, (which is journaled in thesmallerportion of the orifice of this housing,) in order to cause thetail-stock to exert a yielding but suflicient pressure against thearticle to be operated upon to hold it into position, all of which willbe readily understood by the skilled mechanic, as it is embodied inmechanism now in use for handing. A

B and B indicate standards, having mount ed therein a cone-pulley, O,and a head-stock, I). This head-stock has a slightly-conical periphery,and is of a suitable size to fit into the mouth of the glass or articleto be operated upon.

E indicates a frame mounted upon the bedplate at the front of themachine, and having a shaft, F, at its upper part, upon which shaft aseries of pencil carriers or arms, G, G, and G are mounted. These armsor carriers are each capable of an independentmovementupon the shaft, inorder to admit of an independent movement of the pencils which theycarry, to allow them to adjust themselves independently of each other tothe inequalities of the surface of the article operated upon.

K K are adjustable collars, having setscrews for adjusting thepencil-carriers laterally upon any point of the shaft F which may bedesired.

H, H, and H indicate the grinding-pencils, which are adjusted andsecured in the pencilcarriers by means of the adjusting-screws h, h, andk J indicates a wine-glass, held in position between the head and tailstocks.

The operation of my improvement is as follows: A wine-glass or otherarticle to be banded is inserted into position, as shown in Figs. 1 and2, and power is applied, causing it to rotate. The adjustablepencil-carriers are lowered until the pencils press upon the surface ofthe glass, and water and sand or emery or other abradent are caused todrop upon its surface, when the action of the pencils upon the abradentcauses it to abrade the surface, and a series of perfect bands aresimultaneously produced.

If it be desired to regulate the distance of the bands from each other,it may be readily done by inserting various-sized washers between thepencil-carriers upon the shaft F. The wider bands should be producedfrom the action of copper pencils upon the abradent, and for producingtine light bands steel pencils should be employed.

The advantages of my improvement are:

First, I produce simultaneously a series of perfect bands upon thesurface of the article.

Secondly, the bands are produced at accurate and uniform distances apartupon the different articles, thus securing uniformity in the set.

Thirdly, as the pencils are adjustable independently of each other,-eachpencil exerts a uniform pressure upon all parts of the portion of theperiphery it is designed to band, and consequently the banding operationis expedited and time and labor are saved.

I am aware that in similar machines a series of grinding or polishingtools have been employed. said tools laid in notched rests adjustable ina pivoted frame and held against the article operated upon by springs,and I do not herein claim such devices, for the reason that the toolsare not free to adjustthemselves to the surface operated upon withuniform pressure, so as to obtain uniform results. In such machines thedepth of the grinding will depend on the tension of the spring, and, asa consequence, Where inequalities occur on the surface of the glass, thetension of the springs will vary, and the grinding will be, according tothe varying tension. either fainter or deeper, as the case may be. In mydevices the arms or pencil-carriers act by gravity, and the hand must beuniform. One or more of the pencilcarriers can be lifted outof the wayoradjusted during the operation of the machine. The devices are simple,and can be operated by unskilled labor, and there are other points ofadvantage which will be apparent to one skilled in the art.

Having described my invention, what I claim, and desire to secure byLetters Patent, is-

1. In a machine for grinding bands upon glassware, the combination of aseries of indepemlently-pivoted laterally adjustable freelygravitatingpencil-carriers with mechanism, substamially as specified, forhorizontally rotating the article to be operated upon and presenting itto the pencil-carriers, as and for the purpose specitied.

2. In a machine for grinding bands upon glassware, the combination ofthe laterally-adjustable independently-pivoted freely-gravitatingpencil-carriers with the tapering headstock and spring tail-stock,substantially as and for the purpose specified.
